JBLBiotopol - Aquarium Water Conditioner 250ml

I live in a very hard water area and need this when doing a 30ltr water change every 4 to 6 weeks, been using this since I got my fish tank, about 10 or more years ago.

Good product. Easy to measure amount needed due to clear markings on lid.

Use this product all the time! It does what it's supposed to do.Recommended good price too.

Does just what it says on the tin.

Good product, been using it for years.
